Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177822, here are decompositions:
- 11 + 177811 = 177822
- 31 + 177791 = 177822
- 59 + 177763 = 177822
- 61 + 177761 = 177822
- 79 + 177743 = 177822
- 83 + 177739 = 177822
- 131 + 177691 = 177822
- 199 + 177623 = 177822
Showing the first eight; more decompositions exist.
